13 - RECOMMENDED WIRE SECTIONS
Wire sizing is the responsibility of the installer, and depends on
the characteristics and regulations applicable to each installa-
tion site. The following is only to be used as a guideline, and
does not make Carrier in any way liable. After wire sizing has
been completed, using the certified dimensional drawing, the
instal-ler must ensure easy connection and define any modifi-
cations necessary on site.
The connections provided as standard for the field-supplied
power entry cables to the general disconnect/isolator switch
are designed for the number and type of wires, listed in the
table below.
The calculations are based on the maximum machine current
(see electrical data tables).
For the design the following standardised installation methods
are used, in accordance with IEC 364, table 52C:
-
For 30HX units installed inside the building: No.13:
perforated horizontal cable conduit, and No. 41: closed
conduit.
-
For 30GX units installed outside the building: No.17:
suspended aerial lines, and No. 61: buried conduit with a
derating coefficient of 20.
The calculation is based on PVC or XLPE insulated cables
with copper or aluminium core. The maximum temperature is
40°C for 30HX units and 46°C for 30GX units.
The given wire length limits the voltage drop to < 5%.
